REUBEN DEUEL, OF TERRE HAUTE, INDIANA, ASSIGNOR OF ONE-HALF TO JACOB A. PARKER, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 327,388, dated September 29. 1885- l Application filed April25, 1885. (No model.)

To all whom it may concern:

Be it known that I, REUBEN DEUEL, a citizen of the United States, residing at Terre Haute, in the county of Vigo, and State of Indiana, hEWG invented certain new and useful Improvements in Fluid Diaphragm-Meters; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same. a

This invent-ion has for its object to produce a gas or fluid diaphragnrmeter' that shall be frictionless in its action, and will not require that the diaphragm shall be packed nor the shell finished on its inner surface. It is my purpose to supply a dry-meterin which the inflow and the outflow shall be controlled by asystern of mechanism requiring the minimum of parts and oflabor for its construction and the minimum of power to effect its operation with certainty of action. under all circumstances.

To this end my invention consists in a fluid diaphragm-meter having a double concave shell, within which is arranged a flexible collapsing diaphragm for operating the lever mechanism hereinafter described; and it also consists in the construction and arrangement 0 of lever mechanism for operating the valve regulating the inflow and outflow of the fluid.

The ordinary construction and operation of fluid meters require no explanation, save the dominant points most desirable of accomplishment in their constructionviz., cheapness and accuracy in operation.

Referring to the drawings, Figure 1 is an elevation in perspective showing the appcarance of meter and the valve'actuating mech- 0 anism. Fig. 2 is an end elevation. Fig. 3is a side .view partly in section, and Fig. 4 is a detail view. Fig. 5 represents a detachable View of the lever and the diaphragm which actuates it detached; and Fig. 6 represents a 5 transverse vertical sectional view of the meter,

taken on the line at m of Fig. 3.

A represents the shell of the meter, formed of two concave and flanged metal disks joined together by bolts a at their outer peripheries,

L and at the same time clamping the flexible diaphragm B between them. This diaphragm B is constructed so as to present a concave central portion of a contour corresponding to the concave surface of the shell A, and provided with an annular extension or flange, whereby the same may be securely held be: tween the shell-sections by'the bolts a, as indicated. Attached to opposite sides of the center of the diaphragm B are plates b, provided'with a projecting pin, b, which is attached to and operates the lever O. Lever 0 is curved to correspond with the inner curvature of the shell and outer curvature of the diaphragm, and at its inner end is slotted, so

as to admit of free movement of the d'aphragmpin. The outer end of the lever is attached to and operates a spindle, D, having its bearing in the walls of the shell, as shown, and one of the shell-sections is formed with a bulge, s, forming on the interior a pocket for the reception of the lever when forced to that side by the action of the fluid on the diaphragm.

To the outer end of the spindle D is attached a segment, E, and dial registering mechanism. The segment E is provided with pins or stops 6, which have adjustingscrews e, by means of which the movement of the outer lever or spring-arm, F, is regulated or limited in its action when automatically operated to shift the valve, which operation is better explained hereinafter.

To the outer edge or flange of the shell is pivoted centrally a vibrating arm, the lower portion of which is flexible, constituting a spring, the said arm F engaging at its upper end with the adjustable pins 6 of the segment E, and at its lower end with the pins 9 of a segment, G, on the stem of oscillating valve H.

K is a stop or stud to arrest the movement of the oscillating valve.

From the above description it is apparent that while the fluid is filling through the opening I on one side of the diaphragm it is discharging through opening L on the opposite side of the diaphragm until the spring-lever 5 F passes the stud K, when it strikes the pin 9 of the segment G and reverses the valve H, causing an alternate motion or movement of the latter.

The valve may be of any suitable descrip- I tion. In the present instance it is represented as a plug-valve, as indicated by the letter M, having a transverse passage, M, which alternately connects with each side of the diaphragm, and permits the eduction or exhaust alternately at each side of the diaphragm. The induction takes place through the opening I and chamber N of the valve-casing.

The meter may be connected with any suitable register by means of the pawl m and ratchetn, which are acted upon by the spindle D.

The operaton of my improved meter is as follows: The induction I being connected with a proper supply-pipe, and L with the eduction or exhaust pipe, upon admitting the fluid through the supply-pipe it passes through the chamber N into the meter at one side of the diaphragm, forcing the said diaphragm to one side and discharging the contents of the opposite side of the meter through the passage M of the valve and into the exhaust. The valve is then automatically shifted by the valveoperating'mechanism, and the fluid enters at the first-mentioned side of the diaphragm, the exhaust taking place, as before, through the passage M, the position of which is changed by the shifting of the valve for this purpose. This alternate action takes place as long as the meter is in operation, accurately measuring the quantity of fluid passing through.

The construction described renders this form of meter cheap, easily manufactured, durable, and efficient in operation, and of great accuracy.

Having thus described my invention, what I claim is- 1. In a fluid-meter, the combination, with the shell constructed of two parts united together, one of which parts being formed with a bulge or interior pocket, of the intervening flexible diaphragm, the vibrating slotted lever, the central plates and pin connecting said lever with the diaphragm, the rock-shaft and its segment having pins and adjusting-screws, the outer lever, and the'lower segment attached to the stem of a suitable oscillating valve, all substantially as shown and dc scribed.

2. The combination, with the shell of the meter constructed in two parts, as described, of the intervening diaphragm, the central plates, the connecting-lever, its spindle and segment, and the outer lever and lower segment, and suitable valve, the whole arranged to operate substantially in the manner and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

REUBEN DEUEL.
